Question

A(x + 1) - b(x + 1) - x - 1

Answer 1

Explanation:

Solution

I'm assuming you want this simplified. If not leave a note.

a(x + 1) - b(x + 1) - x - 1 remove the brackets

ax + a - bx - b - x - 1 gather like terms

ax - bx - x + a - b - 1

x(a - b - 1) + (a - b - 1) Use the distributive property to simplify

Answer

(x + 1)(a - b - 1)

The common factor is (a - b - 1). That can be pulled out on either side of the isolated + sign
